In this update, the language files get a new template:
Now, all the messages has their category and the help menu appear now in their language file.
Too, now each language has their language name. This is for the command /motd+ language. When u set a language, now appear the language's name. For example, if u set english, before appear en-US, now appear English.
IMPORTANT I recommend reset language files.
Too, delete the sound part in config file. If you don't do this, the sounds don't appear in the config file.
